<Emphasis Type="Italic">Enteromorpha compressa (L.) Greville</Emphasis> an edible green alga as a source of antiallergic principle (S)

Enteromorpha compressa a marine green algal species grows extensively in North coastal Andhra Pradesh. Besides its nutritional importance it has also been identified as source of anti-anaphylactic compound(s).E. compressa extracts alleviated the IgE levels raised against ovalbumin and other allergens in mice. Further,Enteromorpha extract also significantly down regulated the serum IgE levels in different murine models irrespective of their genetic background. The results obtained in this study suggest thatE. compressa extract has compound(s), which inhibit IgE immune response and may have potential in curing various types of allergies.     

Studies on some serum enzyme levels in various liver diseases

Serum alkaline phosphatase (ALP) (EC 3.1.3.1), 5′nucleotidase (5′NT) (EC 3.1.3.5), aldolase (ALD) (EC 4.1.2.13) and sorbitol dehydrogenase (SDH) (EC 1.1.1.14) were estimated in infective hepatitis, alcoholic hepatitis, chronic active hepatitis, obstructive jaundice, cirrhosis of liver and amoebic liver abscess. It was observed that serum ALP and 5′NT were significantly increased in all cases of chronic active hepatitis and obstructive hepatic disease. However, the elevation observed in the latter was much higher than the former. Serum SDH and ALD levels were elevated in all cases of infective hepatitis, studied though increase in the former was much higher than the latter, suggesting its significance in the diagnostic confirmation of this disease. Results presented suggest 5′NT and SDH as more reliable diagnostic test compared to ALP and ALD for obstructive jaundice and infective hepatitis respectively.

青少年网络成瘾、网络偏差行为与一般问题行为的关系

以北京市370名中学生为被试,采用网络成瘾问卷、网络偏差行为问卷、一般问题行为问卷考查了青少年网络成瘾与网络偏差行为的关系,并探讨了两者对一般问题行为的影响。结果表明：（1）网络成瘾、网络偏差行为存在显著的性别差异,男生得分均显著高于女生;网络偏差行为存在显著的年级差异,初一学生的网络偏差行为最多;（2）网络偏差行为与网络成瘾呈显著正相关;（3）网络成瘾者比非成瘾者表现出更多的一般问题行为;（4）网络偏差行为在网络成瘾与一般问题行为的关系中起到完全中介作用。     

浅谈公路工程施工项目成本控制

在目前公路工程施工走向招投标确定项目工程承包的条件下,市场竞争越来越激烈,承包价格走向低势,企业成本较高,结算微利润甚至亏损,直接影响到企业的生存与发展。为提高企业竞争力,本文主要从成本控制的角度,对如何做好公路工程施工成本控制提出了个人的看法及建议,以供业内同行共同参考借鉴。     

基于供给侧结构性改革视角下的老年教育现代化研究

我国老龄人口规模和老龄化速度是世界之最,如果不能妥善解决由此带来的各种社会问题,将严重影响我国社会经济发展的速度与质量。解决当前老年教育发展过程中的不平衡不充分等问题,实现让老年人满意的老年教育目标的关键所在,是根据"党委领导、政府主导、社会参与、全民行动"的新时代老龄工作方针,推进老年教育的供给侧结构性改革,构建社会协同网络,加强互联网+融合,拓展课程资源开放,推动养老服务合作,构建老年教育现代化发展体系。
